"pip配置了需要TLS/SSL的位置，但是Python中的ssl模块不可用". [英] "pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available"

问题描述

我有anaconda软件包并运行Spyder.这是我的系统信息:

I have the anaconda package and run Spyder. Here is my system information:

anaconda                  2018.12                  py37_0

Python                    3.7.1

pip                       18.1

Dell Inspiron 13 7000 64-bit

我无法从命令提示符下使用pip安装任何内容.例如，当尝试安装numpy时(通过anaconda已经拥有)，我得到以下信息:

I am unable to install anything with pip from the command prompt. I get the following when trying to install numpy for instance (which I already have through anaconda):

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Requirement already satisfied: numpy in c:\users\uday rallabhandi\anaconda3\lib\site-packages (1.15.4)

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

请帮助我理解为什么会这样.

Please help me understand why this is happening.

推荐答案

这是我在Windows 10上使用Anaconda纠正错误的过程:

Here was my process to correct the error, on Windows 10 with Anaconda:

1. 为我的环境变量添加了以下路径:
   • /AppData/Local/Continuum/Anaconda3
   • /AppData/Local/Continuum/Anaconda3/Scripts
   • /AppData/Local/Continuum/Anaconda3/Library
   • /AppData/Local/Continuum/Anaconda3/Library/Bin

1. Added the following paths to my environment variables:
   • /AppData/Local/Continuum/Anaconda3
   • /AppData/Local/Continuum/Anaconda3/Scripts
   • /AppData/Local/Continuum/Anaconda3/Library
   • /AppData/Local/Continuum/Anaconda3/Library/Bin

在此阶段，错误消息仍然存在.

At this stage, the error message was still there.

1. 我从Anaconda Prompt安装了最新版本的pip:

1. From Anaconda Prompt, I installed the latest version of pip:

python -m pip install --upgrade pip

python -m pip install --upgrade pip

这似乎可以纠正DLL冲突.

This appeared to correct the DLL conflict.
